Andrena rubricata Smith, 1847.
This species is one of the very few bees that, in Britain, visits only a single flower species for pollen, though it will fly to unrelated species for nectar.
Confined to southern England, where it is known from the Isle of Wight, Hampshire, East Sussex, West Sussex, Surrey, Middlesex, Kent and Essex. There is a number of old unsubstantiated records of this species from Cornwall, Devon, and Suffolk. It is possible that some of these refer to Andrena rosae Panzer, which superficially resembles A. florea. White bryony, the sole pollen source in Britain, is very rare in Devon and Cornwall where it is a probable introduction (Perring & Walters, 1962).
Found throughout much of Europe, from Denmark and The Netherlands, south to Spain and east to Russia. It also occurs in north Africa.
